Expanse of wings 4 inches 7 lines. Rio Janeiro (Stevens). Type, B.M. Subfamily SPHINGINCE. Genus A M P H O N Y X , Poey. 22. A M P H O N Y X RIVULARIS, n. sp. J1. Like a large example of A. duponchel <$, but less green in colour, and with a broader transparent area in the secondaries. Expanse of wings 5 inches. 2 . Like the female of A. duponchel, but slightly larger, the primaries green, not varied with mealy-white patches, and with all the markings distinct as in A. antceus $ . Expanse of wings 6 inches 3 lines. 6 2 , A cS, Ega (Bates); d var., ? (abdomen reddish). Type, B.M. I have little doubt that this is the Upper-Amazon representative of A. antceus, as A. medor* is the Mexican. Herr Julius Flohr, of Hamburg (who has collected much in Mexico), tells me that he has a female example of the latter species measuring 9 inches in expanse of wing ; our female only measures 7 inches. Genus PROTOPARCE f, Burmeister. 23. PROTOPARCE FULVINOTATA, n. sp. Primaries above very similar to P. solani, but lighter, the subapical pale patch less dusky and broader, and all the transverse dark lines * Cramer's locality is (almost certainly) incorrect; w e possess both sexes of his species, distinguished at a glance by its blackish coloration. t I adopt this name, rather than Mr. Grote's emendation of Macrosila, as being one year prior to that genus as first characterized, its type also being indicated as P. rustica. For Macrosila, Walker, I have retained M. incisa, Walker, as type. |
